To all whom it mayv concern: Y

Be itknown that I,` JOHN A. SToL'rMAN, a citizen yof the Unitedl States, residing at Minto, in the county of Valsh and State of- North Dakota, have invented certain new and useful Improvements in. Printing-Machines, of which the following is a. specification, reference being had tothe accompanyingV drawings.

Thisinvention relates-to certain improvements in printing machines, and itis an object of the invention to provide a novel and improved device of this general character especially designed and adapted for use 1n printing upon ligniiied epicarps, Asuch as the v Y shells of walnuts and other edible nuts.

Another-object ofthe invention is to' pro-y vide a novel and improved device of: this general character operating in a manner to produce-on the shellof an edible nut orthe like a suitable symbol wherebyits source of vorigin as particularly rela/tes to production and distribution Ina-y be readily determined. An'additional object of the invention'is to-provide a novel andimproved machine of ythis' general character including a driven l printingicylinder coactingwith a conveyer for the work and which conveyer operates as a bed, together -v with means whereby the work' m'aybe effectively and conveniently distributed upon the conveyer or bed.

The Vinvention consists inthe "details of construction and in the combination and ar# rangement ofthe several parts of irn-` roved rintinv machine wliereb certain important advantages a-reattained and thel device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fullyset forth.

The rnovel features of my invent-ion will hereinafter be definitelyv claimed.

In order thatv my'invention maybetter understood, I will now proceed to de'- scribe the same Vwith reference to the accoml panying drawings, wherein:

Figure 1 is a view in side elevation-of a f printing machine constructed in accordance with anembodiment of my invention.

Fig. 2 is an enlarged fragmentary view of theprinting surface of a stamping roller. Fig. 3 is a view, partlyv in side elevation and partly inverticalsection of the device ashereirin embodied, and

Fig. 4 is a fragmentary view in top plan of the feeding apron as herein embodied.

be the Asdisclosedfin the accompanying drawings,'my improved machine v comprises a Vframe F' including the vertically disposed and transversely spaced sills A between which Vis rotatably supported the stamping roller R.' The stamping roller R includes an axle l extending beyond the opposite end thereof and engaged within the bearing y blocks 2. The blocks 2 are 'arranged within the verticallyV directed slots Siproduced in the sills A, whereby the stamping roller R may be adjusted as the occasions of practice may require; Y l.

An end portion of the shaft'l has fixed thereto a sprocket wheel 4 with which'is engagedfa chain 5. The chain 5 is directed around the vertically spaced sprockets 6 and 7 rotatably supported by a second sill B.

The sprocket 7 is fixed'to the shaft 9 vofthe driving roller 10 for the endless conveyer or bed 11.' Thel stamping roller R may be ltatably supported between a transversely spaced pairjofrsills C. The roller 12 is fixed to a shaft 14 engaged with the bearing blocks 15` adjustably arranged within the substanjusted toward or from the roller 10 as the occasionsof practice may' require and particularly when it is necessary toy effect 'a tightening of the conveyer or bed 11.

I also find it of advantage to have thev lower stretch Z) vof the conveyerl or'bedll y topass over a tensioning roller 17 supported ktially horizontally directed slots 16 produced in the'sills C, so that said roller 12 may be ad- Y between the sills The tensioning'roller 17 is fixed to a shaft 18havi'ng each of its end portions engagedwvith a bearing block 19 1 adjustable within avvertically disposed slot 2() produced' in the adjacent sill A.

The periphery of the stamping roller R isl preferably. of soft' rubber with f the type e carriedthereby of asimilar material and raised thereabove.- In practice, I find it of advantage to have the type raised about onehalf inch so that thev same may effectivelyy engage the work. Each ofthe type c may vio is preferred.

be of any character desired, but it is the purpose of my invention that such type constitute a symbol which will readily determine the origin of the goods stamped thereby and so that the consumer will know the brand of the goods.

Overlying the receiving or rear end portion of the upper stretch a of the conveyer or bed l'lis a delivery table 2l disposed on a desired forward incline and upon which discharges theupper stretch ofthe endlessV feeding apron 22. As herein, disclosed, the

apron 22 comprises a pair of endless sideA chains 23 passing around suitablysupported sprockets 24 carried by the frame F. The side chains 23 are connected byv the cross straps or cleats 25 arranged inl close proximity one to the other but whichserve to carry the nuts or similar work deposited upon-the lupper stretch of the apron 22 to the table 21.` The sprockets -24 are arranged in trans-A versely spaced pairs with the sprockets of each pair fixed to a shaft 26 and the forward shaft 2,6 is operatively connected, as at 27, with the shaft 9, although, if-desired, the apron 22 may be driven in any other manner although the present arrangement Disposed across and above the upper stretch of the apron 22 and adjacent its discharge,

end is a check board 28 which operates to eiiect an even distribution of the nuts or the like upon the apron 22 and to prevent a Y too rapid discharge of the nuts upon the table 2l. v v

I also find it of importance to dispose above the table 21 a check board 29 for the same purposes as has just beeny set forth j relative to the check yboard 28.'` It is preferred,V however, that the check -board29 be vertically adjustable and for which reason the opposite end portions thereof are secured to theverticallydisposed'rods 30 having their opposite end `portions loosely directed through the substantially horizontally disposedsills D. i Engaged with the opposite end portions of said rods 30 and coacting with the sills D are the wing nuts 31v or the. like which, upon proper manipulation, permit the desired raising or lowering of the check. board 29. v

Coacting with the periphery of fthe stampingroller R- is an inking` roll 32 having the shaft 33 thereof rotatablysupported by the vertically swinging arms 34. The arms 34 are pivotally engaged with the upper portion of the frame F and 4coacting with one of said arms 34 is a retractile member whereby the inking roll 32 is constantly urged toward and maintained` in contact with the working face or periphery of the stamping roller R. This mounting of the inking roller'offers nohindrance or obstruction to the desired vertical the stamping roller R.

adjustment ofy AsVv herein disclosed, the retractile mem--l ber 35 comprisespa coil spring having one end portion suitably secured to an arm 34 and its opposite end portion secured to a rod 36 slidably. disposed through the upper portion of the frame F, or more particularly a sill B, and engaged with theV forward endv portion of said rod 3G is a wing nut 37 or the like. This nut 37 coacts with the sill B so that upon requisite rotation thereof, `the tension of the retractilexmember 34 may be regulated.in'accordanoe VWith the require-.,- ments of practice. Y f r The nuts-or the like depositedvuponth-e 11 may be as desired. Under some conditions, it is preferred that the speed of travel of the conveyeron bed 11 be Vless thanfthe peripheral speedz of the. roller R -in order to effectthedesired printing on/the Work,A

although under' other conditions lthe con- 1 veyer orbed l1 may travel-at the same speed.,

or at a greater speed than the peripheral speed of said roller. The rate of speed of Y the conveyer or bed l1 will be best-determined by the diameter of *theVV sprocketv wheel4.

VF rom vthe foregoing description, it is thought tobe obvious thata printing.ma-

chine constructed in accordance Witlimy invention 1s particularlycwell adapted foruse by reasonV ofV the convenience and facility 1 0 5c; v v

with-which it `may be assembled and oper- 1 ated, and it will also be obvious that my inl vention is susceptible of some changel and modification without departing from the principles and spirit thereof and for this reasonI do not-wish-to be understood'asV limiting myself to the precise arrangement `and formation of the several partsherein shown in carrying out my invention in practice except as hereinafter claimed.
